It's not expanding INTO anything. It's just expanding. There are no edges of the universe. It's just that all the points are moving away from one another. Space itself is expanding.

It isn't expanding into anything, the universe as you state is all that exists.
Try to imagine a 2 dimesional universe on a sheet of paper, roll the paper up into a sphere so the surface of the sphere is the universe (noting that the papers edges join at some definate line-remember this line). Now put dots on this surface to represent galaxies. Let the sphere expand (the sphere is not the 2D universe-just it's surface), the dots move apart but have not moved over the surface of the 2D universe but the distances between the galaxies is now greater than it was. The line you remember is still the same in shape and path so the 2D surface hasn't expanded into anything. The same can be imagined mathematically for a 3D universe and so the universe is all that exists but is nontheless expanding.

Bear in mind that when we, as humans , talk about our universe , our thinking is stuck in 3 ( or 4 if you count time) dimensions.
There are ( or as far as we can tell) many more dimensions ( I don't think anyone agrees on how many though).
I couldn't even begin to explain it - but I like to think about expanding into other dimensions as it were ( which is rubbish in terms of the definitions I know).
I remember reading a book about hyperspace which suggested that when/if our 3d universe collapses , an advanced civilization could retreat into other dimensions. And it was a serious book, not sci-fi.
Suffice to say , many dimensions , very confusing, who knows ? One day someone will though.
Maybe someone else knows more about this area.

As the universe fills a greater space does the pressure contained in the space decrease or is matter created to maintain a constant pressure? If matter is neither created or destroyed will the universal pressure eventually become so low that solids will disintergate? Is there a name fro this universal pressure?

Its expanding just that its more acurate to say that its creating space ruder then its expanding its space within it self like it was making distance ruder then making anything else

Wow - good question!! I think that the edges of the universe are the definitive edges of everything, and when the universe expands, the edges of the universe also spread outwards.
Difficult concept to get your head around.
You've confused me now!
*goes to watch Doctor Who in the hope of it explaining universal phenomena*
*fails*

It's not actually expanding "into" anything. It's creating space and time as it goes.

It isn't expanding "into" anything. All the distances between all the galaxies is increasing as more space is being created between them. That's what expansion means.

it is not expanding into anything as such. infact if the teories are true then it will expand forever, even our nearest star proxmi centuarua, as it is called. is receding away from us. kinda like balloon, if you mark on the surface of the balloon with any marker and blow the air into it. you will see that the spots u marked are moving away from it

I find the bigger house I have, with more storage space, I still manage to fill it. I guess the universe is just the same.
